Mylnvention relates to IIllXlIlg apparatus,iand more particularly to apparatus for mix ng foodgmaterials forlive stock, but it *oth'erkin'ds5 I I One object of my invention is to provide apparatus for effectively mixing materials into'which' is"introduce'da liquid content such as molasses,'for exampleJ i- 5 vide in combination with a mixing apparatus,-meansfor more effectively removing the mixed materials therefrom.

A further object'of my invention is to providean improved means for charging the materlals'to the mixing apparatus; Anotherjob'jectf ofmy invention is to provide' means for moreefl'ectively circulating materials during a mixing'operatlon and for 2'0 intermixing the materials reproduce a thorough dissemination of the various ingredients through the resulting-mixture.

Stillanother object of'my invention is to simplify and improve generally the structure and operation of apparatus of the character referred to.-

A conveyer chain 10 which carries vanes l l'moves through a continuous path thatexteridsupwardlythrough the conduit 8 and returns to the lower end of the mixing chamber through a casing 12. The conveyer also passes through a charging chamber or material-receiving chamber or hopper 13'th'at ismounted below the floor level and has communication with the hopper 7 A charging "ope'ning 14 is provided in thefioor and such Another object of my invention is to pro-1 opening maybe covered by a platform or plate 15 when material'is not being dumped into the hopper 13. a maybe employed in mixing materials of I through the casing 12.- The chain is driven -by the sprocket wheel 18 from a shaft 19 which carries a pulley 21 that may be driven from any suitable source of "power, the shaft 19- having driving connection through sprocket wheels and a chain 22 with a'shaft 20- which carries thesprocket wheel 18.

It will be seen that when materials are introduced-- into the "charging chamber 13,

they will be caught by the moving vanes of the conveyer and carried through the conduit 8. The materials are discharged at the-upper end of the conduit 8 in the form of a spray and fall or sink into the hopper 7.

The materials are'charged into the chamber '13, until a sufficient quantity has accumu-' lated in the mixing. chamber 6 or until such 7 a. I I chamberisnearlyfull. One form ofapparatus by which my in- 1 Continued travel of theconveyer will circulate the materialrepeatedly throughthe v conduit- 8 to effect thorough intermixing 30 a view, thereof partially inside elevation and thereof." If molasses or some other mixture has to be incorporated in the mixture, it

'may be introduced into the mixing chamber,

1 of the 'conduit to the hopper 7 it will be p v 1 broken upby" toothed rollers 25 whichare The apparatus includes a m-ixing chamber arranged-in rectangular formation in the hopper"? and; are driven from the shaft 19 by belt drives-26 a'nd27 The toothed rollers serve to effectively mix the various ingredients andare particularly useful if molasses orsome other liquid is beingincorpo- 12.. A deflecting plate38 is providedin pivoted at 31 and carries a crank arm 32, while the trough 29 is loosely mounted 011 the shaft which carries the sprocket 17 and has a crank-like extension 33. The extension 33 is connected through toggle links 34: to the trough 28.

Ordinarily, the troughs occupy the positions shown in Fig. 1, so that there will be no interference with circulation of the materials in the mixing chamber.

After the materials have been tho'roughly mixed, the crank arm 32 is rocked in a counter-clockwise direction by meansof a hand lever 35 and a link 36, thus swinging the trough 28 upwardly and moving the trough 29 in a clockwisedirection, to the positions shown indotted lines in Fig. 1.

The movement of the trough 29 into position over theconduitS is causedby the bottom of thechute 28 engaging the toggle links .34 during upward movement of such chute. A pin-37 is mounted in the side wall of the chute 28 to breakthe toggle and to retract the chute v29 when the chute 28 is being swung to inoperativeor retracted po- ,end of the conduit 8 laterally to the casing such casing, to direct the ;material toward the outer Wall thereof and to a position whereit will fall tothe'discharge spout 39 of ;the casing.

It, will be seen that the downwardly-moving run, ofthe conveyer chain 10 is inclined and that the .vanes 11 thereof slope toward theouter wall of theicasing :12. This ar- --rangement results in any liltitflriitl which falls upon the upper sides. of the descending vanes '11 being deflected still further laterallyztoward :the discharge spout 39.

Another advantage arising from directing ,the conveyerathrough; a generally hori- Zontal path attheupper end of thelmixing chamber .residesinthe fact'that it enables the return run of the conveyerto lie outsideLof the mixing chamber. If both verticalfrunsof theconveyer were located entirely the mixing chamber, it will .be seen that there would.be,a tendency for a portion only of the materials to be circulated by the6conveyer, leavingthe other portions thereof undisturbed.

The dischargespout is controlled by a valve 41 which is operated by a handle .42. Whenithe handle 42 is raised, the upper edge of the valve 41 is swung toward the conveverchain, thus permittingmaterial to fall through the spout 39 into sacks or other receptacles ,placed therebeneath.

The hinged ;plate ,15 serves not .only as a platform, but asa cover ,for the chamber 13. NVhen the chamber l3 isbeing charged,

-whichcarries-the sprocket 16, are secured po lygonally-shaped discs or plates 1-8 against which the lower ends of the arms 45 bear, the .weight of the platform 15 serving to hold such lower ends in engagement with the discs ,48. As the shaft 47 rotates, the discs 4.8 will cause oscillation of the arms 45 about their pivots 4:6, thus vibrating the platform 15 and effecting settling and compacting of the materials in the bags being filled.

Certain of the vanes 11 carry wiping strips 11, as shown more clearly in Figs-4 and 5, to serve as scrapers and prevent accumulation of material against the walls of the conduit 8. These strips may be of fiber boardor any other suitablematerial.

The apparatus above described is shown as mounted within a framework 50 of angle bars and the like-that are suitably secured together to form a unitary structure with the workparts, so that the entire apparatus can. be shipped in assembled condition and conveniently installed at the place of use.
